Referring iirst to Figs. 1, 2 and 4, the vending machine includes ahousing having a base I0 and an outer casing II. One side wall of theouter casing is provided with a door I2 hinged thereto by hinges I3 andlocked in place by a suitable lock I3a. The housing is provided with acover I4 having a thick layer of thermal insulating material thereinwhich is hinged in place on thehousing by a hinge I5 and is held in aclosed position by latches I6 accessible from within the housing whenthe door I2 is opened.-

The right side of the housing is provided with a partition I8 to dene aspace I9 between the partition and the door I2 for the operatingmechanism of the vending machine.

The housing is, also, provided with an inner casing 20, the front andrear walls of which are formed of evaporator plates 2l for refrigeratingthe interior of the inner casing. The space between the inner casing 20and the outer casing II is filled with thermal insulating material sothat refrigerated articles may be maintained within the inner. casing 20with the greatest possible eiilciency. The evaporator plates 2| areconnected to a conventional refrigerating apparatus located in thebottom of the housing on the base I0 and this refrigerating apparatusmay include the usual compressor 22, expansion valve and condenser 23.Air for condensing purposes enters through louvers 24 in the door I2 andthen passes downwardly through the compartment I9 and over the condenser23 and out thru a passage 25 adjacent the base I Il. The compressor ofthe refrigerating apparatus may be thermostatically controlled in aconventional manner yfor maintaining the desired refrigeratingtemperatures within the inner casing 20.

A storage compartment 21 is removably received within the inner casing20 and the storage compartment may include front and rear walls 28 andside walls 29, the front and rear walls converging in a semi-cylindricalbottom wall 30. Preferably the front and rear walls 28 are located as-closely as possible to the evaporators 2I so that4 maximum coolingefiiciency is obtained.V Space is preferably maintained between the sidewalls 29 of the storage compartment and the inner casing 20 inV orderthat releasabley connecitions may be included between these two membersto permit removal of the storage compartment from the inner casing.

lesser number of wheels. The various article re-v ceiving pockets 36 ofthe two rows of pockets are in alinement with each other. The sidewalls'29 of the storage compartment also rotatably support an ejectoroperating shaft 31.

Referring now in more detail to Figs. 3, 5, 6 and '1, the belts 35 areprovided with a plurality of holes 46 which are adapted'` to receiveprojections 4I on the periphery of the wheels 34 so that upon rotationof the wheels 34 a positive drive is provided for advancing the belts 35and the pockets carried" thereby. The pockets 36 are formedof lightweight" sheet metal and are spot welded to the beu-.s 35 which areformed of flexible sheet metal. Preferably the spot'welded con-l nectionis made adjacent the bottom of the pockets so that the pocketssmayexwith respect to the belts as indicatedin Figs: 5,'6 and 1. The

pockets are preferably provided with ledges 43 whichclosely approach thefront and rear walls andthe bottom wall of the storage compartment toprevent articles'from falling from the pockets. The rear pockets arealso provided with a plurality of openings 44 which, as will be pointedYout in' more detail hereafter, are adapted to receive ejectors forejecting articles-from the pockets.

' The' articles vended by the machine of thisI invention may be of*any-type, but preferably they are ice cream bars ysuch asillustrated'at 45v in Fig. 3A and which may ybe providedwith Suitablesticks' 46. The pockets are of such size as to receive the articles tobe vended.

Adjacent each side-'wallf26 of the storage compartment the ejectoroperating shaft -31 carries a crank`56 which `is connected by a pintoune end of a link 52', theother endof which is connected by apin 53 toa1ever1'54 pivoted at55 to-a bracket 56 secured to the side Wall `29 ofthe storage .compartment. The crank '56fandtl'ie link 52 form atogglezforoscillating the lever54 about itsk pivot 55. The outer end ofeachlever 54 is secured to -a shaft-,51. A plurality of vejectors arecarried by, the shaft 51 and areheld in spaced yrelation by 'spacersleeves 58 as shown in more detail in Fig. 13. The =ejector`59 operatesto eject articles from one row' of pockets at a relatively highelevation and the ejector 66 operates'to eject articles from-the otherrow lof pockets' at a relatively low' elevation as will be seenby-compa-ring Figures 6 and 7. To this endfthe-'ejector 59 is providedwith a hole 62 and a communicating arcuate slot 63 and likewise theejector `66.is provided with a corresponding hole 64 and a communicatingslot 65. The ejectors59 and 66 in the assembly of the machinea-readapted to .be slid over the upper conveyor shaftv 3.2.this beingpermitted by the enlarged .holes 62 and 64. The upper conveyor shaft 32is providedwith a plurality of longitudinally spaced peripherialgrooves66 for receiving the arcuate .slots .63 and-65 :of the ejectors. Whentheejectors areproperly located the slots 63-.and 65 are received `inthe grooves so that the ejectors areV properly positioned and carried bythe upper yconveyor shaft l3--2 and Ythe shaft 51.l Theupper ends ofeach-ejector 5.9 and 66-have pusher surfaces 61 which enter in theopenings r44 4 in the pockets 36 for ejecting articles therefrom.

The vending machine includes a discharge passage having bottomwall 16which terminates at a high elevation 1l with respect to one row ofpockets and at a low elevation 12 with respect to the other row ofpockets. The discharge passage also has side walls 13 for directing theejected yarticles to`a door 14 carried for pivotal movement by a shaft15. The door has side Walls ,16 and connects with a discharge tray 11carried on the outer surface of the housing. A sealing gasket seals thedoor when the door is closed.

The door is opened during the time that articles are discharged'throughthe discharge passage. The Shaft 15.which carries the door 14 isprovided with a crank arm 16 which is pivoted atf86 Vto one endof a link8|, the other end of which .is pivoted at B2 to a crank 83 carried by ashaftA 84. Thus, when the shaft 84 is rotated the door 14 is opened andclosed. Preferably there isprovided'a stripfcfinsula'ting material 84adjacent theY door and-Voperating-l' mechanismf therefor to' prevent'the operating-mechanism and door yfrom becoming so cold as tocondenseand freeze moisture thereon.

Referring now to Figs.v 5; 6;'5 7`and'11, Figs. 5 andillustrate"thefipositions of the' parts of'the conveyor7 ejectors and*door for` the discharge passage when'the vending machine is 1 atl rest.When it is desired Ito vendan'articlea mech-y anism described in'more-'detail 'hereafter operatesA these parts in timed relation.In-'the'cycle of operationthe door 14? is' opened 'andthe conveyor is'advanced a distance equal to one half the distancev between the pockets36J to`4 they positionillustrated y.in Fig; 6 .fwherein thev adjacentpockets' of the two 'rows'ofipockets vline iupwith .the lower edge 12ofthe dischargepassage 16.' The ejecr tors 59fand '66emeoperatedifromthe position shown in Fig. 5 to the positions'shownin'Figs'. .6 and 7.- l'nderxthese:` conditions vtlleejector'lUoperates-to eject an "article'from" its associated pocket. overthe-'edge 12.- into the Y. discharge passage 16 and out through the-door14 into'v the discharge tray 11; 'hey ejector'59 has rio-effect at thistime forit extends-above? the article in its associated pocket. The dooris thenrclosed* and theejectors vreturnedto the posit'icn'illustrated inFig. 5 while the conveyorrremair'is in' the position illustrated YinFig:-The vending-machine is again .at rest"untilanother article is tolbeejected therefrom.` l

. Uponfthenext oper-ation of themachine ther door 14 is opened, theconveyor is advanced'one half .the distancezbetweenf-thepockets from theposition shown-.in Fig. 6 to r-theposition shown in Fig; .'1 andthen-theejectors 59-and 66 are advanced.v Inthe latter. position-ofthe?conveyor4 the pockets line up with the upper edge 1I of the"discharge. passage. 1:6. The-:ejector 56A urges `the article from itsassociated passage .over the upperI edge 1l intothe dischargepassage 16andout through the door 14 into the discharge. tray 11. At this'time theejector 66 jhasno effect since the article has previouslybeen`ejected'from its associated pocket. Following'thisdispensing operationthe ejectors are -1 returnedrv to the position shown in Fig. 5 and-thedoor'14 is-closed andthe vending'machine is again' ati'rest. The'conveyor assumes a position corresponding to thepostion illustrated inFig; '5"andiisready for another cycle of operation.

' Thus'the vending machine includes -a conveyor having two rowsofialinedi pockets, offset discharge passages and offset ejectors. Oneach;

vending 'operation the ejectors and discharge passage door are fullyoperated and the conveyor is advanced one half the distance between thepockets to provide for dispensing one article at a time from the alinedpockets of the two rows of pockets. This action permits the storage of amaximum number of articles in a minimum storage space.

The upper conveyor shaft 32 journaled in the compartment 21 extendsoutwardly beyond the wall 29 thereof and is provided with a crank arm 90having a hole therein for receiving a pin 9| carried by a crank arm 92which in turn is carried by a shaft 93. The shaft 93 is journaled in abracket 94 and is connected by a sleeve 95 made of vthermal insulatingmaterial to a shaft 96 journaled at 91. The sleeve 95 of thermalinsulating material operates to decrease materially the transfer of heatbetween shafts 96 and 93 so that the parts of the mechanisms exterior ofthe shaft 99 will not condense and freeze moisture thereon. The innercasing 20 is provided with an enlarged opening 86 through which thecrank arm 92 may be retracted when brought in alinement therewith. Thus,the pin 9| may be withdrawn from the hole in the crank arm 90 to permitupward removal of the storage compartment 21 when desired.

The outer end of the shaft has secured to it aflatch collarv 98 having alatch surface 99 and a disc is rotatably mounted on the shaft 96adjacent the latch collar 98. The disc |00 is provided with acircumferential slot |0| for adjustably receiving a pivot pin |02carrying a latch arm |03 which is urged against the latch collar 98 by aspring |04. When the disc |00 is rotated in a clockwise direction asillustrated in Figs. 9 and 10, the latch lever 03 engages the latchsurface 99 of the collar 98 to rotate the shaft 96 and hence advance theconveyor. The conveyor may be manually advanced with respect to the disc|00 for loading purposes, this being permitted by the one-way connectionafforded by the latch collar 98 and latch lever |03. The latch lever |03may be adjustably positioned in the slot |0| for alining the positionsof the conveyor and the disc |00. The disc |00 is also provided with ahole |05 and with notches |06 on the periphery thereof to cooperate withan index |01 mounted on the partition I8. The notches may have indiciaassociated therewith so that the position of the conveyor in the storagecompartment may be visuallyv determined by reference to the position ofthe disc |00.

The ejector operating shaft 31 journaled in the storage compartment 21also extends beyond the side wall 29 and carries a disc |08 providedwith a tongue |09 which is received in a groove of a complimentary disc||0 carried by a shaft When the ejectors are in the retracted positionas illustrated in Fig. 5 the tongue and groove of the discs |08 and |09are vertically arranged. Thus, when the crank arm 92 associated with theconveyor shaft is retracted through the opening 86, the storagecompartment with the parts carried thereby may be freely lifted from theinner casing 20. The shaft is connected by a sleeve ||2 of thermalinsulating material to a shaft ||3 which carries a disc ||4 providedwith a tongue ||5. The sleeve ||2 of thermal insulating material greatlyreduced the conduction of heat by the shafts ||3 Iand to preventcondensation and freezing of moisture on the exterior of the shaft ||3.

Referring now more particularly to Figs. 9,

10 and 12, the door l2 is provided with three brackets' |20 carryingheaded pins |2|, for re ceiving slots |22 of a supporting plate |23. Theplate |23 and various parts carried thereby are, therefore, removablysupported by the door |2. A ratchet wheel |25 in the form of a disc isrotatably mounted on vthe plate |23. The disc |25 is provided with aplurality of circumferentially arranged pins |21 and a plurality ofperipheral notches |28 in radial alinement with the pins |21. The disc|25 also carried a pin 2|'9 to be received in the hole |05 of the disc|00 when the door 2 is closed. Thus, rotation of the disc |25 istransmitted through the pin |29 to the disc |00 and through the latchlever |03 to the collar 98 and through the crank arm 92 and pin 9| tothe crank arm for yadvancing the conveyor. The distance between the pins|21 corresponds to one-half the distance between the pockets of theconveyor. The pin |29 on the disc |25 and the hole |05 in the disc |00affords a releasable connection between the two discs, the connectionbeing released when the door |2 is opened.

The supporting plate |23 carries a pair of brackets |32 for slidablyreceiving -a member |33 which in turn carries a rack |34. A pawl |35 ispivoted at |36 to themember |33 and is urged by a spring into engagementwith a stop pin |31. The pawl 35 cooperates with the p-ins |21 on thedisc |25 for rotating the disc.

A lever |38 is pivoted at |39 to the supporting plate |23 and carries apin |40 and is provided with a cam surface |4| adapted to enter thenotches |28 in the periphery of the disc |25. The pin |40 rides in a camslot |42 in the member |93. The cam slot |42 therefore operates to pushthe cam surface |4| of the lever |38 in the peripherial notches |28 foraccurately alining the position of the rachet wheel disc 25.

A pawl |44 is pivoted to the supporting plate |23 at |45 and a springnormally urges the pawl into engagement with a stop pin |46.

The mexnber |33 also carries a pair of spaced abutments |48 and |49which are adapted to engage a pin |50 carried by a crank arm |5| whichin turn is carried by Ia shaft |52 journaled on the supporting plate 23.The shaft |52 carries a disc |53 provided with a groove for receivingthe tongue |5 of the disc I4. Thus, the crank |5| is connected to theejector operating shaft |31 by a releasable connection afforded by thetongue and groove.v When the door |`2 is open the connection is releasedand when the doorl 2 is closed it is remade. Stops |54 associated withthe crank arm |5| limit the extent of'movement of the crank arm. f

With the parts in the position shown in Fig. 9 the vending` 'machine isat rest and backward movement of the conveyor is prevented by the pawl|44 engaging 4a pin |21. When the member |33 is slidably advancedtowards the right as illustrated in Fig. 9, the pawl 35 engages a. pin|21 and rotates the ratchet wheel disc |25 a distance corresponding tothe distance between pins |21. After the disc 25 has thus been advancedthe cam slot |42 operates on continued movement of the member |33 toengage the cam surface |4| in a peripherial notch |28 for accuratelyalining the disc |35 as is illustrated in Fig. 10. When the disc |25 isthus advanced and alined the pawl |44 engages a pin |21 to preventreverse movementof the disc |25. Towards the end of the movement of themember |33 the abutment |48 engages the pin |52 to mnvethe crank .arm|5.|` to the position's'hewn in Fig. '1.0 whereby the ejectors lin thestorage lcompartment are operated. lUpon :retraction 'of "the member4,33 to the .left from the :position shown inFig. Ltotheposition.shownin .Fig 9 :the cam surface Mi .is `.withdrawn from theperipherial mitch |28 and the pawl |35 slides over the :pin |2f1 forresetting the mechanism -for the :next cycle lof operation. Towards theend'of the retract-ing movement of .member l|33 the .abutment .M9engages the `pin |51] of the crank arm |54 to return thencrank armito:theposition shown in Eig. 9 whereby ...the ejectors .are :returned tothe position shown :in.Fig. 5. The parts arethen restored =to Lthezposition shown in Fig. 9 :and ready for aanother \cycle :of operation.

The door ;|2 .as :illustrated 2in Fig. =8 carries a bea-ring |60 `for`rotatably receiving .the shaft 'The `outer -end vottheshat |.6.| isprovided with a hanzlle -MZ held vin place thereon `by "a screw |53. Theshaft ifl is also provided with a fspr-.ing -lll .for retaining vthehandle |52 in :a vertical fposition. The shait :|61 icarries a gear |65which meshes with the rack |34 of the member 1.33 so that when the:handle A|62 is pulled the member |33l is :advanced-'and when the .doorL62 is released, the spring 454 loperates to -retract the vmember f|33`and return the handle |62 to Ithe vertical position.
